Concrete needs protection. Left unprotected, the surface is exposed to carbonation, chloride ingress, freeze-thaw damage, chemical attack, water penetration and UV degradation. Every one of these mechanisms shortens the service life of the structure. Applied correctly, a protective coating or waterproofing system can extend that service life by decades, at a fraction of the cost of the reactive repair that will otherwise follow.
Protective coatings and structural waterproofing are related but distinct disciplines. Coatings sit on the surface and protect the concrete from atmospheric and chemical exposure. Waterproofing systems prevent water penetration through the structure itself, whether from above (deck waterproofing), below (basements), or at ground level (tanking). CRS delivers both, often on the same project, using systems specified to match the structure and the exposure environment.
On the coatings side, we install anti-carbonation coatings to slow the ingress of atmospheric CO2 and protect embedded reinforcement. Elastomeric coatings for façades where crack-bridging capability is required. Chemical-resistant coatings for industrial floors, tank interiors and secondary containment. Decorative fair-face coatings where appearance matters alongside performance.
On the waterproofing side, we install liquid-applied deck membranes for car parks, plaza decks and podium slabs. Structural waterproofing systems for basements, tanks and below-ground structures, delivered against BS 8102 requirements. Crystalline waterproofing admixtures and surface-applied systems. Movement joint waterproofing where the joint detail is critical to overall system integrity.
Materials are selected from approved system suppliers including Sika, Weber and Mapei. Installation is delivered by trained applicators to the system manufacturer’s specification, ensuring warranties remain valid and long-term performance is maintained. Surface preparation is critical to every coating and waterproofing system, and CRS delivers preparation to the specification the system requires.
